IMPROVEMENT IN HARVESTER-RAKES.

Specification forming part of Letters Patent No. 111,344, dated January31, 1871 antedaf ed January 28,1871.

I, GEORGE W. HINES, of Brookfield, in the county of Waukesha, in theState of Wisconsin, have invented certain Improvements inHarvester-Rakes, of which the following is a specification Nature andObject of the Invention.

The object of my invention is to sweep the grain from the platform andgather it together, so that it can be bound without raking it uptogether after it falls on the ground, by means of the deviceshereinafter described.

Description of the Drawing forming part of this Spectficatton.

Figure I is a plan or top view, Fig. II is a side view, and Fig. III isa sectional view, of the rake.

G eneral Description.

Ais the platform. B is the outer guard; C, the inner guard. These twoguards are contracted at their outer ends, so that the grain may bebrought into a close compass ready for binding as it leaves theplatform. D, the guard-board; E E E, the stops, screwed or bolted ontothe outer guard and onto the platform, to hold the guard B firmly inposition. These stops may be changed out or in on the platform, so as tocontract the discharge-opening, as desired. F, the rake-head; 65111113screwed onto the outer end of the rake; H, rake-teeth.- These teeth areset in blocks that work in the grooved head of the rake. I, springs tokeep the rake-teeth apart; K, a sheave or truck in the end of the middletooth, to make it roll easily on the platform; L L, loose rings on thetwo outside teeth; M, wheel which the rake is attached to, and whichrevolves the rake; N, track which raises the rake out from between theguards as it is revolved round; 0, dropper, which the grain, as it fallsfrom the platform, drops onto and rolls off onto the ground; P, springswhich hold the dropper up when the grain is not on it; Q Q, stops on theplatform, which the springs P are around; It, swing-guide, which holdsthe grain from spreading as it falls onto the dropper; S, wire springwhich throws this swing-guide back at the moment the grain falls ontothe dropper; T, catch which holds swing-guide up; U, spring on catch Tto hold the catch out in place; V, a lever, hung by a screw or boltabout one-third the distance from the end, attached to catch T, so thatwhen the rake-head comes round it strikes the upper end of this leverand throws catch T back, releasing it from swing-guide R; W, roller; X,a cord running from swing-guide It, behind roller W, to lever Y; Z,lever on the upper end of shaft 07, so that when the rake-head strikesagainst its end it will turn the shaft and swing .out lever Y and drawswing-guide up, which, striking against the chamfered end of catch T,throws it back, the guide passing behind the catch, and the spring U,throwing the catch back, holds the guide up till the rake-head releasesit by striking lever V; a, an iron on the inside of the guard B, on theend of which is. swingguide It. Against this iron a the ring on theouter tooth strikes, and, following around, presses the teeth uptogether and contracts them in the head of the rake. b, an iron on theinside guard, 0, against which the ring L on the inside of the rakestrikes, and the teeth are pressed out together; 0 0, stops which fastenguard O to the platform; e, pin which passes through the back end ofdropper O, and which the dropper moves on, as shown by dotted lines; (I,shaft.

The rake-head is intended to be made as described, or I sometimes makeitwith two heads, with the teeth permanent in them, and slide the twoheads by each other and throw them back with a spring.

Sometimes I make the rake-head of three pieces, the middle piece beingstationary and the two end pieces sliding inward, with the teethstationary.

The operation of this rake is quite simple. The rake-head is broughtround with any kind of machinery suitable for the purpose, the teeth ofthe rake striking in at the butts of the grain and shoving it along onthe platform.

The rings L L on the two teeth, at the outer and inner end of therake-head, strike against irons a and b on guards B and G, and, as therake passes round, press them in toward the center, the outer end of therake striking lever Z. turning it, and lever Y pulling on cord X, whichdraws in swing-guide It, throwing back stop T, and as the rake-headpasses lever Z the cord X is loosened, the spring on stop T throws itout again, holding guide R till the rake comes up and strikeslever V andreleases it, and the guide swings out again, the grain having droppedonto the dropper, when it bears the dropper down and the stub ble sweepsit off onto the ground, and the rake is raised, passes round, and goesthrough the same operation again.

Claims.

I claim as my inVention- 1. The combination of the adjustable guards Band O with stops E and 0, irons a and b, and rake F, arrangedsubstantially as described.

2. Bake F, provided with nut G, teeth H, springs I, and rollers L,operating substantially as described.

3. The combination of the guide B, stop T, lever V, lever Y, cord X, andlever Z, operating substantially as described.

4. Dropper 0, arranged to operate in combination with rake F and guideR, substantial] y as described.
